The Algorithm Behind the Curtain
Computer algorithms guide and propel decisions we make every day, from the shows we choose on Netflix to the purchases we make on Amazon. Algorithms also operate behind the scenes of our professional lives. Susan Nevelow Mart, director of the University of Colorado Law School library, recently published a study (see https://bit.ly/2GJBmwW) that compared how six legal search platforms reacted to identical keyword queries. She and her team looked at the first 10 cases retrieved by Westlaw, Lexis Advance, Fastcase, Casetext, Ravel Law, and Google Scholar. She found, on average, that each platform listed four cases that did not appear within the first 10 results of any of the other platform’s top10 results.
